Turbo question
Turbo Mini Forums

hello

can anyone tell me something about the standard spec Renault 5GT spec T2 turbo.

How is the lag on it, max power respond

Thanks

Please explain more!

What are we talking about? a standard R5GT or the turbo charger on aa A series mini/metro??

Either way very little lag.

Hello

Mirage MS delivers 3 types of turbo
1.standard spec Renault 5GT spec T2 turbo.

2. Hybrid T2, using alternative trim compressor, reprofiled T2 Compressor
housing, £60 degree thrust bearing. Tailored to provide maximum response and
top power of 120bhp

3, Hybrid T2.5 centre bearing carrier, T2.5 compressor & housing
(reprofiled), t2 turbine housing, 360 Degree thrust bearing. Tuned to
provide power of 180bhp

Does anyone have any exp. with one of them?

The only things i have heard about Mirage is they take ages to produce the goods!!

Yup same here...

a T3 comes on boost at 3k its hardly a problem and certainly cheaper!!

Thanks alex

Do you know the power it can deliver?

Buljac

as much as you want !

As much as you can afford is another way to Say it!!

My boost accidently peeked at 35psi once(T3), if that charge was cooled effectively what sort of bhp would "A SORTED" a series produce in power!

T2 = nice shopping car

T3 = animal

IMO.

so dave and jim drive shopping cars lol!

im sticking with my animal for the mo

I like my shopping car!

jim`s is a shopping cart , he just fills it with expensive things

Everyone knows that instructions only have to be read if the thing doesn't work....

I shop at expensive places! Actually there places that sell expensive things cheap

Quite a harsh comment. I'd like to let you all know that we are not a mail order house for mini stuff. We are a race team primarily and this keeps us very busy, we are not even in the uk for a few months each year. The mini turbo manifolds etc only came about because of my own interest in it. Those of you who have spoke to me will know that i'm just an enthusiast like the rest of you and am happy to chat about your projects and ways you can save money on bits etc.

We currently have manifold kits sat on the shelf. We did have a problem with our last batch of manifolds as we changed the way they were manufactured, with different flanges. My manufacturer had also upgraded to a much better mandrel tube bender. This resulted in a delay of a few months while we got the problem sorted. These manifolds are quite complecated to make accuratley in numbers. I can only appologise for this.

Turbos i can supply within 14 days normally. I don't keep them on the shelf as yet. They are not of the shelf items with my supplier, each is made on a per order basis, so i'm at the mercy of my supplier. This does give the advantage that i can tailor any unit to your requirements.

T2 = nice shopping car
T3 = animal
= Sorry this is rubbish

what about the T2,5?

Witch rev dose it pump up at, and what power output dose it give?

Thanks again for all the answeres.

Mirage: I will soon make an order from you, just need to find out of witch parts to order. Any recomandations?

thanks again.

It depends what you want from your engine. Really think (honestly) how you will use and drive the car. Even with the smaller T2 you will have bags of power.

You cant say how much power a specific turbo gives as it depends on the engine and the installation. The figures i quote for the 2 hybrids are there throughputs at best efficency. The T2 based units will quite happily provide you with 150bhp as it is quite happy with higher boost pressure.

Hey mirage... I will soon be purchasing a T2 maybe from yourselves . Could you please give some estimates of price and information for the various types that you supply..
I'm looking for around 150 bhp

I knew dnam well someone would pipe up with "so you think my car is a shopping car!"...well jim and dave are two players in the turbo field!!..Jim could you pop me to safeways later!...

What i am saying is a T2 is far less laggy but a T3 can deliver more power. So you must decide what the car car is going to be used for, a big question!!

A lot of people fall flat on their face because they believe all they hear, do your own research and reap the results on the advice you choose to take.

I would be interested to see what people thik of the T2, turbo, what sort of maximum power to people think is capable of?

Jon, take my focus to safeways, boots bigger, more room for beer.

Can i have the sat nav on??

if you like mate!

it`ll take you the long way round!!

And what im saying is you are are wrong !
Giallofly, what is the spec of your turbo ? If it's metro a t2/t2.5 built correctly will blow it in the weeds on response and ultimate horse power.

It all depends on what components go into making the turbo. The T number refers only to its "familly" size if you like. There are many different specs, a T2 can be built to a myriad of different specification, as can a T3.

Granted if we were blowing a higher displacement engine then the a T3 based unit would be the way to go due to its ability to ultimatley flow a higher mass of air. But what you must think about is, is your engine capable of burning this amount of air ???? A good T3 (not a metro one !!) can flow enough air for 300bhp if you can use it. You can build a unit around T2.5 components that will flow enough air to satisfy any A series. My T2.5 hybrid is set up for optimum effeciency around 180bhp, it is capable of more at higher boost pressure. This unit still uses a T2 turbine and housing even at this power level.

I dont make this info up, through motor racing i'm fortunate enough to work with some of the best engine builders and tuners on the planet and these guys really know what they are talking about. These guys are used to building engines where non of you on this page would be able to sell your minis and buy me a set of valves and springs with the cash !

i suggest a bit more research for some.

well from a few of my mates running renault 5 turbos, i know that t2's will fairly reliably produce 25psi in standard trim, that makes about 180bhp on a r5, on a mini i would guess they would be good for about 150ish?

And on the 7th day........... God created turbochargers!

My T3 turbo charger is not in standard MG Metro form, won't go into it fully but it is stuff that is done DIY in the garage.

Mirage, am i correct in thinking your manifolds were designed for ease of fitting into a mini with no bulk heads mods needed? It is a good idea indeed but how do you think the efficiency of your manifold the stock item as your ports 1 and 4 directly oppose each other in terms of flow, where as the the OE item is nicely routed to flow the exhaust gases into the turbine housing. There is room for improvement on the OE item with a bit of porting as i have done.

The Metro T3 is an old piece of kit and i understand the later turbos have moved on as technology does, but we understand i am sure is not ONLY the turbo charger that produces the power. Obviously head, cam choice,charge cooling, fuel,exhaust, ignition set up etc etc all contribute to a sorted set up capable of putting people "in the weeds".

Jon.

what about the T2,5?????
